THE RESULTS are not definitive, but a preliminary report on sudden acceleration from the National Highway Traffic Safety Administration (NHTSA) has some good news for Toyota Motor Corp. Of the 58 data recorders analyzed by the agency and the company, 35 showed that the brake pedal was not depressed at the time of the crash. Partial braking was involved in 14 other cases. Drivers were hitting the gas pedal instead of the brake. In short, electronics was not the issue. Human error was.
